Realta Fusion today announced an oversubscribed $36 million Series A round to bring its compact, scalable, modular magnetic mirror fusion technology closer to commercialization.

Future Ventures led the round with participation from Mayfield, GSBackers, SiteGround, Avila VC, and other investors. Existing Realta Fusion investors Khosla Ventures, Wisconsin Alumni Research Foundation, and TitletownTech also participated in the round.

Realta Fusion spun out of an experiment at the University of Wisconsin-Madison funded by the U.S. Department of Energy's Advanced Research Projects Agency - Energy. The experiment was the first to use high temperature superconducting magnets in a magnetic mirror configuration and confined its first plasma at a world-record breaking magnetic field strength of 17 Tesla.
